Parr Instrument Company Model 2811 Pellet Press The convenient and inexpensive way to make pellets, tablets, and wafers for oxygen bomb calorimetry, emission spectroscopy, molecular weight determinations, animal feed experiments, and other laboratory purposes. 2811 Designing and Building High Precision Combustion Calorimeters for 120 Years

The Parr 2811 Pellet Press provides a convenient means for compressing powdered materials into pellet or tablet form without a heavy investment in expensive tablet-making machinery. It is a compact, hand-operated press that can be used anywhere in the laboratory, requiring very little bench space and no fixed mounting, producing uniform pellets in a polished stainless steel die and ejecting them smoothly into a stainless receiver without danger of contamination. For Bomb Calorimetry Pellet making is a very important step in bomb calorimetry, particularly when working with finely powdered samples....

using the maximum force of the press. When compressing light or fluffy materials the die can be raised after successive punch strokes to compensate for the reduction in the volume of the charge. The variable anvil setting can also be used as a means for adjusting the amount of pressure applied to a pellet. If duplicate pellets of equal density are desired, these can be made by using equal amounts of sample and leaving the anvil at a fixed setting while taking the punch through its full stroke when forming each pellet. Construction Features The Parr pellet press is sturdily constructed with its...
